From the pioneering days of Geysers in the late 1950s and early 1960s, Ecolaire has applied both its field and in-house test results to produce reliable designs in both surface and direct contact geothermal condensers.
Under construction is this 30 MW geothermal surface condenser with a six pass water side arrangement designed to serve the dual purpose of providing district heating and power for the people of Iceland.
In operation, it will raise the cooling water inlet temperature by almost 100°F for the purpose of district heating and will also provide a vacuum at the end of a low-pressure turbine-generator for high efficient power production.
Due to the highly corrosive geothermal environment the condenser has been designed with Titanium tubes and tube sheets in addition to internal support structures and an outer body made of 316 stainless steel.
This noncondensible gas removal system including precooler has multiple ejectors to match capacity to actual noncondensible flow.
Unique to geothermal units is the extremely large amount of noncondensibles, as much as 10% or more of the steam flow. By comparison a typical power plant has less than 1/10% noncondensible flow. Ecolaire product designs include allowances for the heat transfer degradation by the noncondensibles and minimize vapor carryover to reduce gas removal equipment power consumption.
Turbine exhaust transition piece for a geothermal condenser is fabricated entirely from SS 316L. To negate the effects of corrosive steam, geothermal condensers are typically constructed entirely of stainless steel.
Our 184,000 square-foot manufacturing facility is qualified to handle virtually any high-alloy material required.
